Background: Infective endocarditis is a life-threatening condition and is associated with embolic events. We aimed to evaluate the association of vegetation size, multiplicity, and position with cerebral embolism and late mortality in patients with infective endocarditis.

Methods: We retrospectively reviewed patients with infective endocarditis who were admitted to a single institution between November 2005 and August 2017. A total of 419 patients with infective endocarditis were included in the study, 273 of whom had undergone surgery. The primary endpoint was all-cause mortality, and the secondary endpoint was cerebral embolism. Multivariate Cox regression and logistic regression analyses were performed to identify independent risk factors for 30-day mortality, late mortality, and cerebral embolism.

Results: Age (hazard ratio [HR] 1.02; 95% confidence interval [CI], 1.00 to 1.04), renal failure (HR 4.21; 95% CI, 2.67 to 6.65), surgery (HR 0.31; 95% CI, 0.21 to 0.46), and Acute Physiology and Chronic Health Evaluation II score (HR 1.08; 95% CI, 1.01 to 1.15) were associated with late mortality. Vegetation size, multiplicity, and position were not significantly associated with late mortality, but a mitral vegetation size of greater than 10 mm (odds ratio 2.25; 95% CI, 1.32 to 3.84) was an independent risk factor for cerebral embolism.

Conclusions: A vegetation size of greater than 10 mm and the mitral position were found to be significant risk factors for cerebral embolism, and for this group, early surgery might be considered to prevent cerebral embolism.
